[0002] The embodiments of the present application relate to the field of display interaction technology, and in particular to a display module and a display device. Background Art

[0003] Haptic feedback technology provides timely and useful information through the sense of touch, enabling interaction between users and electronic devices. This technology elevates the user's sense of touch, enabling them to access information faster and more accurately in their daily lives and work. Haptic feedback technology has been widely used in smartphones, tablets, wearable devices, VR / AR, and other industries, providing users with a more immersive experience.

[0004] Current haptic feedback technology typically uses motors or piezoelectric actuators to vibrate the display screen, creating a mechanical sense of touch to address distraction during driving or surgery, thereby improving safety. In teaching and training, scenario simulation, and entertainment, providing more realistic tactile feedback can enhance the interaction between vision, hearing, and touch, and increase the user's sense of interaction with virtual interfaces or game scenes. However, current technology can only achieve basic mechanical button functions such as confirmation, reminders, scrolling, and sliding through simple vibrations, and cannot simulate more complex tactile experiences such as the texture and grain of materials touched by fingers.

[0018] Embodiments of the present application provide a display module and a display device to solve the technical problem in the prior art that display devices cannot provide the tactile sensation of texture and texture during tactile interaction.

[0019] The specific implementation of this application is described below through examples:

[0020] As shown in Figures 1 to 4, an embodiment of the present application provides a display module, comprising: a display function layer and a touch component. The touch component is disposed on the light-emitting side of the display function layer. The touch component includes: a touch layer 170; a touch control layer 150, which is connected to one side of the touch layer 170 and outputs the sliding speed and pressure value when the touch layer 170 is operated by a user; a control unit 200, which is connected to the side of the touch layer 170 away from the touch layer 150 and obtains the sliding speed and pressure value; in response to the pressure value, the control unit 200 controls the touch layer 170 to provide feedback of a pressing sensation to the user; and in response to the sliding speed, the control unit 200 controls the touch layer 170 to provide feedback of a texture sensation to the user. Specifically, the touch layer 170 is the portion exposed to the outside and directly interacts with the user. Generally speaking, the touch layer 170 is the outermost glass structure of the display screen of an electronic device such as a mobile phone, tablet, or computer. Users can interact with the electronic device by performing operations such as clicking, sliding, and pressing on the touch layer 170. Generally, the touch layer 150 comprises either a capacitive touch layer or a resistive touch layer, or a combination of both. The capacitive touch layer comprises a transparent conductive layer overlying the display layer. This layer contains tiny capacitor nodes that can detect changes in charge from a human body or a stylus. When a finger or stylus touches the touch layer 170, touch data such as sliding speed and pressure are measured by changing the capacitance, which is then transmitted to the modulation unit for processing. The resistive touch layer, on the other hand, consists of two stacked conductive layers, interconnected along two horizontal axes. When pressure is applied to the touch layer 170, the resistance between the conductive layers changes. By measuring this change in resistance, touch data such as sliding speed and pressure are determined and transmitted to the modulation unit for processing. The control unit 200 is a control component electrically connected to the touch layer 150 and the modulation unit. It includes a piezoelectric actuator. The control unit 200 controls the deformation of corresponding locations on the touch layer 170 based on sliding speed and pressure. Generally speaking, the position where the touch layer 170 is deformed is the same as the position where the user touches the touch layer. Through different deformations, the user can obtain a more realistic touch feeling during operation, thereby improving the user's experience when operating the display device.

[0021] As shown in Figure 1, this embodiment of the present application further includes a modulation unit, which is connected to the touch layer 150 and the control unit. The modulation unit is used to modulate the voltage signal and frequency signal obtained by the touch layer into a pressure value and a sliding speed. In response to the pressure value, the control unit 200 controls the touch layer 170 to deform to simulate a pressing sensation; in response to the sliding speed, the control unit 200 controls the touch layer 170 to vibrate to simulate a textured sensation. Specifically, the sliding speed refers to the speed of horizontal movement of the touch layer 170 when the touch layer 170 is operated. When a user slides a finger across the touch layer 170, the touch layer 150 detects the contact time between the finger and the multiple touch units. The modulation unit then determines the finger's sliding speed based on the time difference detected by the multiple touch units. Similarly, the pressure value refers to the force applied vertically to the touch layer 170 when the touch layer 170 is operated. When the user presses or clicks, the touch units output different voltage values. The modulation unit determines the specific pressure value based on the corresponding relationship between the voltage value and the pressure. The control unit 200 controls the touch layer 170 to vibrate according to the finger sliding speed, causing the user's finger to move up and down during the sliding process, thereby allowing the user to feel the texture of the surface of the touch layer 170. The higher the frequency of the vibration, the denser the texture, and the lower the frequency, the sparser the texture. The so-called texture is manifested as uniform raised or recessed lines or bumps. At the same time, the control unit 200 controls the touch layer 170 to deform according to the pressure value of the finger pressing, so that the user can feel the touch layer 170 being pressed when pressing the touch layer 170. The pressure sensation can simulate the soft and hard materials of the surface of an object when pressed, such as soft materials such as silk, leather, cloth, etc., and hard materials such as stone, wood, metal, etc.

[0022] As shown in FIG1 , in the embodiment of the present application, the modulation unit obtains the amplitude and stripe spacing of the pre-stored pattern, where the amplitude includes the maximum amplitude; the display function layer includes a plurality of pixel units, and the modulation unit calculates the sliding frequency according to the sliding speed and stripe spacing. The specific formula is: f e1 =v e1 / d e1 ;

[0023] Where, d e1 is the stripe spacing; f e1 is the sliding frequency; v e1 is the sliding speed; the maximum frequency f e1 Can reflect the finger sliding speed v e1 Distance d from tactile pattern e1 The relationship between (as shown in Figure 5); finger sliding speed v e1 The peak-to-peak value variation time t of the output signal of the pixel unit in the touch layer 150 can be p1 and the pixel unit spacing d p1 The calculation formula of sliding velocity is: e1=d p1 / t p1 ;

[0024] Where, d p1 is the distance between adjacent pixel units; t p1 is the change time of the peak-to-peak value in the pixel unit output signal;

[0025] Output the maximum amplitude and sliding frequency in sinusoidal form to obtain the frequency signal. The specific formula is: A e1 ×sin(2πf e1 t);

[0026] Where, t represents time; A e1 represents the maximum amplitude; π represents the ratio of circumference to circumference. Specifically, the frequency signal includes an excitation signal (as shown in FIG6 ). The frequency signal controls the touch layer 170 to generate excitation (i.e., up and down movement), thereby causing the user's finger to slightly jump up and down on the touch layer 170. The regular jumping combined with the sliding speed of the finger can give the user the illusion that the surface of the object being touched has a texture. Furthermore, the frequency signal is controlled based on the coordinates of the user's touch on the display screen and the spacing of the stripes in the texture of the pattern at that coordinate position, allowing the user to feel the continuous changes in the texture, deepening the user's experience.

[0027] In some embodiments of the present application, the pre-stored patterns are obtained by constructing corresponding analysis models to simulate or experiment on different tactile patterns to obtain the spectrum distribution of different tactile patterns, as well as the mapping of spectrum diagrams and materials. And further construct the excitation frequency and deformation degree to be output when different sliding speeds and pressure values ​​are obtained for different materials and users in different operating modes, and continuously correct them through multiple experiments and simulations and multiple users. A mapping relationship is established between the obtained tactile pattern and one or more data of material, spectrum diagram, excitation frequency, sliding speed, pressure value and deformation degree. And the mapping relationship is pre-stored in the memory of the display module or display device for direct call by the processor. Stripe spacing refers to the distance between the textures of different materials in the tactile pattern. For example, if there are multiple stripes in wood, the distance between adjacent stripes is the stripe spacing. The stripe spacing can be the average value of the distances of multiple adjacent stripes, or it can be the actual distance between adjacent stripes.

[0028] In some other embodiments of the present application, the modulation unit obtains a pre-stored frequency spectrum and fringe spacing of the pattern, and obtains an amplitude and a frequency according to the frequency spectrum, wherein the amplitude includes a maximum amplitude;

[0029] The display function layer includes multiple pixel units. The modulation unit calculates the sliding frequency based on the sliding speed and the stripe spacing. The specific formula is: e1 =v e1 / de1 ;

[0030] Where, d e1 is the stripe spacing; f e1 is the sliding frequency; v e1 is the sliding speed;

[0031] The sliding velocity is calculated as: v e1 =d p1 / t p1 ;

[0032] Where, d p1 is the distance between adjacent pixel units; t p1 is the change time of the peak-to-peak value in the pixel unit output signal;

[0033] The amplitude is combined with the sliding frequency and the frequency is output in a sine form to obtain the frequency signal. The specific formula is: Σ(A ek ×sin(2πf ek t));

[0034] Where A ek ∈(A e1 ,A e2 ,…,A en ), represents the amplitude; f ek Indicates frequency or sliding frequency, selected from (f e1 ,f e2 ,…,f en ); n represents the number; k is a value between 1 and n; t represents time in seconds; and π represents the ratio of pi. The pre-stored pattern spectrogram is used to visualize the signal frequency distribution of the corresponding pattern in the displayed image. The spectrogram can display the energy or intensity of the pattern at different frequencies. Spectrograms typically use frequency as the horizontal axis and signal intensity or energy as the vertical axis. The spectrogram can be further analyzed to determine the material of the corresponding pattern in the displayed image.

[0035] In some other embodiments of the present application, the modulation unit obtains a pre-stored pattern spectrum and fringe spacing, and obtains an amplitude and a frequency according to the spectrum, wherein the amplitude includes a maximum amplitude; the control unit 200 has a resonant frequency;

[0036] The display function layer includes multiple pixel units. The modulation unit calculates the sliding frequency based on the sliding speed and the stripe spacing. The specific formula is: e1 =v e1 / d e1 ;

[0037] Where, d e1 is the stripe spacing; f e1 is the sliding frequency; v e1 is the sliding speed;

[0038] The sliding velocity is calculated as: v e1 =d p1 / t p1 ;

[0039] Where, d p1 is the distance between adjacent pixel units; t p1 is the change time of the peak-to-peak value in the pixel unit output signal;

[0040] The amplitude is combined with the sliding frequency and the frequency is output in a sine form to obtain the frequency signal. The specific formula is: Σ(A ek ×sin(2πf ek t))×sin(2πf p t);

[0041] Where A ek ∈(A e1 ,A e2 ,…,A en ), represents the amplitude; f ek Indicates frequency or sliding frequency, selected from (f e1 ,f e2 ,…,f en ); n represents the number; k is a value selected from 1 to n; t represents time; f p Represents the resonant frequency; π represents pi, and the frequency signal ranges from 2 to 16 Hz. It is understandable that the frequency signal includes 2 Hz, 3 Hz, 4 Hz, 5 Hz, 6 Hz, 7 Hz, 8 Hz, 9 Hz, 10 Hz, 11 Hz, 12 Hz, 13 Hz, 14 Hz, 15 Hz, and 16 Hz. In some other embodiments of the present application, the frequency signal may also be less than 2 Hz or greater than 16 Hz, and the specific selection may be based on actual conditions.

[0042] In some other embodiments of the present application, the modulation unit obtains the material of a pre-stored pattern and the pressure applied by the user. In response to the first type of material and pressure, the modulation unit controls the deformation of the touch layer 170 in the same direction as the pressure; in response to the second type of material and pressure, the modulation unit controls the deformation of the touch layer 170 in the opposite direction of the pressure. Specifically, the first type of material is a softer material such as cloth or leather, while the second type of material is a harder material such as stone, wood, and metal. Generally, the touch layer 170 is a planar structure, and the direction perpendicular to the plane of the touch layer 170 is perpendicular to the surface of the touch layer 170. Therefore, the two opposite directions are the outward and inward directions perpendicular to the touch layer 170. When the direction is outward, at least a portion of the touch layer 170 convexes outward; when the direction is inward, at least a portion of the touch layer 170 concave inward. By controlling the convexity and concavity of the touch layer 170, the tactile sensation of the corresponding pattern on the display can be simulated. When the touch layer 170 is concave, it can be easily pressed, and the user experiences a softer touch. When the touch layer 170 is convex, it is difficult to press, and the user experiences a harder touch. Therefore, by controlling the deformation direction of the touch layer 170, the touch sensations of different materials can be simulated, thereby improving the user experience.

[0043] In some other embodiments of the present application, the surface of the touch layer 170 has some curvature, that is, the surface of the touch layer 170 is curved inward or convex outward. In this case, the plane perpendicular to the touch layer 170 is represented by the plane formed by the tangent line at a certain point on the touch layer 170. In this case, the inward concavity and outward convexity of the touch layer 170 are based on the plane formed by the tangent line. Similarly, when the touch layer 170 is concave inward, the touch layer 170 can be easily pressed, and the user can experience a softer touch when touching or pressing; when the touch layer 170 is convex outward, the touch layer 170 is difficult to press, and the user can experience a harder touch when touching or pressing. Therefore, by controlling the deformation direction of the touch layer 170, the tactile feel of different materials can be simulated, thereby improving the user experience.

[0044] In some other embodiments of the present application, different materials have varying degrees of hardness and softness. Therefore, to enhance the user experience with touch layer 170, the touch layer 170 is manipulated to simulate different materials based on the tactile pattern spectrum and in combination with simulation and experimentation, resulting in different degrees of deformation of touch layer 170. This degree of deformation can further enhance the user's tactile sensation when operating touch layer 170, thereby improving the user experience. It should be noted that the degree of deformation of touch layer 170 can be zero, meaning that touch layer 170 does not deform.

[0045] In some embodiments of the present application, the tactile pattern's spectrum, texture, and serial number can be pre-set and stored in the display module's memory. When the tactile pattern is displayed, the processor can directly retrieve the spectrum, texture, and other information corresponding to the tactile pattern. When the touch layer 150 detects a user operating the touch layer 170, the control unit 200 controls the touch layer 170 to vibrate and deform according to the user's finger movement speed, thereby simulating the corresponding tactile sensation and texture, providing the user with a more realistic experience.

[0046] As shown in Figures 1 and 2, in an embodiment of the present application, the display module comprises a display area 100 and a non-display area 300, which surrounds the display area 100. A control unit 200 is located in the non-display area 300. There are at least two control units 200, and the two control units 200 are arranged opposite each other. Specifically, the display area 100 is used to display the image, and the non-display area 300 is generally an extension of the display area 100. The non-display area 300 is used to connect to a fixing component to fix the display area 100. To avoid obstructing the image in the display area 100, the control unit 200 can be located in the non-display area 300. The opposing control units 200 can control any position of the touch layer 170. By controlling the deformation speed, direction, and degree of the touch layer 170, the touch feeling of different materials can be simulated, thereby enhancing the user experience. In some other embodiments of the present application, the control units 200 can also be located on the four sides of the display area 100, that is, in the four directions of the non-display area 300, as shown in Figure 3.

[0047] As shown in Figure 4, this embodiment of the present application also includes an alloy layer 400. The alloy layer 400 is connected between the control unit 200 and the touch layer 170, and the alloy layer 400 is connected to the touch layer 170 via an adhesive layer 180. Specifically, the control unit 200 is positioned on the surface of the touch layer 170 that contacts the user, and the alloy layer 400 secures the control unit 200 to the touch layer 170. The control unit 200 is typically made of piezoelectric ceramic material, which has excellent piezoelectric properties but relatively low mechanical strength. To increase the mechanical strength and durability of the control unit 200, the alloy layer 400 is connected to the surface of the touch layer 170, thereby increasing the deformation of the control unit 200 when controlling the touch layer 170. Due to the high strength and wear resistance of the alloy material, it effectively protects the piezoelectric ceramic and increases the lifespan of the actuator. The alloy layer 400 also provides improved electrical conductivity. The control unit 200 requires an electric field applied by electrodes to stimulate the piezoelectric ceramic to deform. Alloy layer 400 has excellent electrical conductivity and can be connected to the piezoelectric ceramic as an electrode, ensuring effective electric field transmission and excitation. Furthermore, alloy layer 400 provides improved thermal conductivity. The control unit 200 may generate significant heat during use, and alloy layer 400 effectively conducts and disperses this heat, preventing overheating from impacting the performance of the control unit 200.

[0048] As shown in Figure 4, in this embodiment of the present application, touch layer 150 is located on the side of touch layer 170 away from control unit 200. Touch layer 150 is connected to touch layer 170 via adhesive layer 160. Specifically, touch layer 150 is connected to the bottom of touch layer 170. When a user operates touch layer 170, touch layer 150 can directly access the corresponding data on touch layer 170. Furthermore, adhesive layer 160 allows touch layer 150 to be more tightly connected to touch layer 170, preventing touch layer 150 from missing user operations on touch layer 170.

[0049] As shown in Figure 4, in the embodiment of the present application, the touch component also includes an adhesive layer 160, and the touch layer 150 is connected to the touch layer 170 via the adhesive layer 160; an alloy layer 400 is provided between the control unit 200 and the touch layer 170, and the alloy layer 400 is connected to the touch layer 170 via the adhesion layer 180; the display function layer includes a second polarizing layer 140, a filter layer 130, a transistor layer 120 and a first polarizing layer 110; the second polarizing layer 140 is located on the side of the touch layer 150 away from the touch layer 170, the first polarizing layer 110 is located on the side of the second polarizing layer 140 away from the touch layer 150, and the filter layer 130 and the transistor layer 120 are located between the second polarizing layer 140 and the first polarizing layer 110; wherein, the filter layer 130 is close to the second polarizing layer 140, and the transistor layer 120 is close to the first polarizing layer 110. Specifically, the first polarizing layer 110 is used to convert the generated light into polarized light in a specific direction. The transistor layer 120 is composed of multiple tiny thin-film transistors, each of which can be used to control the brightness and color of a pixel on the liquid crystal screen. The transistor layer 120 is equivalent to an electronic switch, which adjusts the light transmittance of the liquid crystal molecules by controlling the on / off state of the transistor; the filter layer 130 is a color filter layer, which is composed of red, green and blue primary color filters. The three color filters can filter out other light and only the color of the three filters can pass through; the second polarizing layer 140 is used to filter the light passing through the filter layer 130 again to ensure that only light with a specific polarization direction is transmitted.

[0050] As shown in FIG3 and FIG4 , based on the same technical concept of the present application, an embodiment of the present application further provides a method for controlling touch sensation of a display module, the method comprising:

[0051] S1: The touch layer 150 outputs the sliding speed and pressure value when the touch layer 170 is operated by the user. Specifically, the touch layer 150 is connected to the touch layer 170 and obtains the corresponding sliding speed and pressure value when the user clicks, slides, or presses the touch layer 170.

[0052] S2: In response to the pressure value, the control unit 200 controls the touch layer 170 to provide the user with a sense of pressure. Specifically, the touch layer 150 receives the voltage signal and frequency signal generated when the user operates the touch layer 170. The modulation unit modulates the voltage signal into a pressure value based on the relationship between the voltage signal and the pressure value. The modulation unit, which includes a processor of the electronic device, transmits the pressure value to the control unit 200. The control unit 200 controls the deformation of the touch layer 170 based on the pressure value, thereby providing the user with a sense of pressure. The sense of pressure can range from soft touch, such as cloth and leather, to hard touch, such as stone and metal.

[0053] S3: In response to the sliding speed, the control unit 200 controls the touch layer 170 to provide the user with a sense of texture. Specifically, the touch layer 150 receives a frequency signal generated by the user's operation of the touch layer 170, and the modulation unit calculates and modulates the frequency signal into the sliding speed. The modulation unit transmits the sliding speed to the control unit 200, which controls the vibration of the touch layer 170 based on the sliding speed, thereby providing the user with a sense of texture. Texture can range from a rough feeling like gauze or mesh to a smooth feeling like silk or leather.
